发明名称 FUSE MONITORING CIRCUIT FOR SEMICONDUCTOR MEMORY DEVICE
摘要 A fuse monitoring circuit for a semiconductor device includes a repair fuse unit including a number of fuses to which a repair address is programmed, and configured to output fuse state signals corresponding to the connection states of the respective fuses in response to a fuse initialization signal. A serial fuse monitoring unit is configured to output a fuse state monitoring signal corresponding to each fuse state signal selected by an applied address in response to a serial monitoring test mode signal. Also, a parallel fuse monitoring unit is configured to output a repair monitoring signal by comparing an applied address and the repair address in response to a parallel monitoring test mode signal. An output unit is configured to output the fuse state monitoring signal and the repair monitoring signal to an output pad in response to an output control signal.
